CZ131 / CW606N - Riviting & Turning Brass
CW606N / CZ131 is a riveting and turning brass with a duplex phase structure containing a fine dispersion of lead particles to improve machinability. In addition the alloy offers a high general corrosion resistance combined with a good strength and ductility.
The CW606N / CZ131 has a high enough copper content to retain good cold heading and cold forming properties together with the ability to be crimped and knurled. Typically used for the production of headed components and is the ideal choice for components requiring forming and machining.
